In my current occupation I’m constantly in contact with advertising and editorial staff across a range of magazines. I have found that what Scameron says to be generally true; despite magazine’s insisting that they always maintain “independent journalistic integrity”.
If you spend enough money with some you can even get a copy of the article before it goes to print so you can correct any “technical” inaccuracies.
P.S.
Scameron, have you recently celebrated a birthday?
